Let's review the information provided to us to answer the question correctly:
In 1 batch of muffins , there is 2/3 cup of raisins
Ina made 2 1/2 batches of muffins
Solution:
1. We will convert fractions and mixed numbers to decimals
2/3 = 0.66
2 1/2 = 2.5
2. We will use Direct Rule of Three to answer the question, as follows:
Batches Cup of Raisins
1 0.66
2.5 x
3. We solve for x, this way:
1 * x = 0.66 / 2.5
x = 0.66 * 2.5
x = 1.66
4. We convert the decimal to mixed number
1.66 = 1 + 2/3
1.66 = 1 2/3
Answer: Ina used 1 2/3 cups of raisins to make 2 1/2 batches of muffins
As we can see, apparently 1 2/3 cups is not a choice as an answer. However, we can notice that option A is equivalent.
If we simplify 1 4/6, dividing by 2 the fraction, we will get 1 2/3.
Therefore, answer A is the correct because 1 2/3 abd 1 4/6 are equivalents
